empty the receiver of the bobbins contained therein.

During weft replenishing operations of a loom the depleted bobbins are pushed downwardly out of the shuttle by the incoming fresh bobbins, and it has been customary in the past to provide removal thereof from the It is another object of my present invention to In carrying my invention I prefer to use two parallel cross bars on the frame spaced sufficiently to hold the receiver against substantial angular movement relatively to the guideways and also serving as a convenient hand hold by which the receiver may be removed from its support.

In the following description I set forth two different means for supporting the bobbin receiver, one of these comprising an upright secured to the lower part of the loom frame, and the other comprising a suspended hanger above the bobbin receiver. The latter form of support permits adjustment of the bobbin receiver laterally with respect to the path of the outgoing bobbin and also in a direction toward and from the lay.

With these and other objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth.

In the accompanying drawings, wherein two forms of the invention are shown,

Fig. 1 is a side elevation partly in section showing the preferred form of my improved bobbin receiver and its support, the receiver being in normal bobbin receiving position,

Fig. 2 is a front elevation looking in the direction of arrow 2, Fig. 1,

Fig. 3 is a plan View looking in the direction of arrow 3, Fig. 2,

Fig. 4 is a detail vertical section on line 44, Fig. 3,

Fig. 5 is a diagrammatic view showing the manner of removing the bobbin receiver from the support illustrated in Figs. 1 and 2,

Fig. 6 is a view similar to Fig. 1 but showing a modified form of bobbin receiver support,

Fig. 7 is a front elevation looking in the direction of arrow I, Fig. 6,

Fig. 8 is an enlarged vertical section on line 8-43, Fig. 7, and

Fig. 9 is a front elevation of the upper part of the modified supporting structure looking in the direction of arrow 9, Fig. 8.

Referring particularly to Figs. 1 to 5 which illustrate the preferred form of the invention, 1 have shown a loom frame Ill and a lay l 1 swinging about a rocker shaft [2. The lay is reciprocated backwardly and forwardly by means of connectors one of which is shown at l3. A shuttle box 5 3 is carried by the lay and receives the shuttle S on alternate beats of the loom. Secured to the lay and depending from the shuttle box is a bobbin uide chute i5 which is inclined downwardly and forwardly. During a weft replenishing operation the bobbin B shown in Fig. 2 is pushed downwardly out of the shuttle S and is guided by the chute l5 along a downwardly and forwardly extending path. This operation occurs when the lay is at its so-called front center position shown in Fig. 1.

In carrying my invention into effect I provide a spent bobbin receiver designated generally at R including a cloth bag 20 and a metallic frame designated generally at 2!. The latter may be made of a single piece of metallic tube bent as indicated in Figs. 1 and 2 and having a bottom 22 connected to right and left ascending side members 23 and 24, respectively. Each of these members is bent rearwardly at its upper end to provide a bag supporting arm 25 which as shown more particularly in Fig. 1 is inclined downwardly and rearwardly.

The bag 20 may be made flexible cloth material and the arms 25 as at 26. upper part of the bag of any appropriate is suspended from Straps 27 secured to the extend around the side members 23 and 24 to prevent the bag from sliding rearwardly off the arms 25, and a bottom strap 28 secured to the bag extends forwardly around the side members adjacent to their lower ends to restrict back and forth swaying of the bag 25 relatively to frame 2|.

In the preferred form of the invention-I provide a stationary support 38 having a foot 3| at the lower end thereof bolted or otherwise permanently secured to the loom frame H]. An. upright 32 rising from the foot is provided with a horizontal member or arm'33 supportingright and left guideways 34 and 35, respectively; as shown in Figs. 2 and 3. These guideways are constructed as shown moreparticularly in Figs. 1 and 4 and provide forwardly andupwardly inclined slots 35 which open forwardly. These slots are located between top and bottom side rails 3'1 and 38, respectively, which are joinedv at their rear ends to form a stop 39, see Fig. 4.

The receiver frame 21 is provided with front and back parallel horizontal cross bars 40 and M, respectively, which are permanently secured to and extend between the supporting arms 25. Cross bar 4| is behind and somewhat lower than bar 48 when the side members are vertical as shown in Fig. 1. These cross bars are ordinarily located in the slots 35 as indicated in Figs. 1 and 4.so that the frame 2| is suspended from the member 33 and held against back and forth swinging or vibration during loom operation. The guideways 34 and 35 are sufficiently close to their respective support arms 25 to prevent substantial lateral movement of the receiver R along member 33 in a directiontoward and away from the loom frame.

When the bag 2|! is sufficiently full of depleted bobbins to require emptying the operator will grasp the two bars All and 4| between the guideways 34 and 35 and slide the receiver R forwardly. During this movement the receiver will also rise somewhat due to the inclination of slots 35, but the rear ends of the arms 25 will ordinarily be located far enough below the chute l so that they willnot engage the latter during I this forward and. upward movement of the re-v ceiver. It. will be noted particularly in Fig. 1.

that the cross bars 45 and 4| are forward of a vertical line passing through the center of the bag, and because of this relationship the bag and receiver will tend to swing forwardlyaway from the lay and move the support arms 25 downwardly with respect tothe bobbin chute as soon as the cross bars are out. of their guideways.

After the bag has been emptied of bobbins the receiver R will be returned to the normal position. shown in Fig. 1 by causing the rear cross bar 4| to enter the slots .35, after which the receiver is moved rearwardly until the front cross bar 40 is also located in the slots 35.. Because of the relation of the center of gravity of the bag and the cross bars, as already described,

the front cross bar 4|] may be slightly above the slots 35 when the rear cross bar first enters the slots, but a slight downward motion of the front cross bar by the attendant will enable the bar 45'. to enter the slots 36, after which both cross bars are slid rearwardly untilthe rear bar 4| comes against the stops 39 at the rear of the guideways. The manner of moving the receiver forwardly from its normal position is indicated in Fig. 5, wherein the dotted lines indicate the usualposition of the receiver and the full lines. indi-.- cate a position which the receiver. can occupy during removal of the receiver and after the cross bars and 4| have been removed from the slots 36.

The modified form of bobbin receiver support shown in Figs. 6 to 9 hangs from a support above the bag 20 and the bag supporting arms 25. As shown in Figs. 6 and 7 the loom is provided with a magazine supporting foot 5|] from which extends a stud 5| substantially horizontal and parallel to the lay. This stud in effect is the support for the transfer mechanism not shown by which the depleted bobbins are pushed out of the shuttle S. The bobbin receiver support designated generally at 52 comprises two parts the upper or which serves as a hanger 53 and the lower ofwhich is aguideway supporting member 54. The hanger 53 is provided with a hub 55 held'in fixed position on the outer end of stud 5| by: set screws 55. As shown more particularly in Fig. 9 the hanger 53 has a web 51 the right andleftends of which are formed with upwardly opening slots 58'. The bottom member 54 has upwardly extending arms 59 which register with theslots 58-and are held to the hanger by bolts. 50.

The. bottom member 54 is. provided with a cross bar.6| atthe ends of which are located right and left guideways 62 and 63; respectively. These guideways. are similar to the guideways describedjforv the'preferred form of the invention and. provide upwardly. and forwardly extending. slots 55 which open forwardly and receive thefront and back cross bars 40 and 4| respectively of the frame 2|. The same receiver R' is used-for both forms of supports therefor.

The set screws 56 permit the hanger 52 and therefore th'ebobbin. receiver R to be adjusted angularly as viewed bobbin chute l5, and also laterally as viewed in Fig.7 toward and from the loom frame Hi. This adjustment permits the receiver tobe placed correctly with respectto the path traversed by the descendingdepleted bobbins. It is believed that the manner of removing the receiver R; from the modified form of support will be apparent from the description already given in describing .the preferred form .of the invention. The slots 65 permit the bars 40 andA to be slid forwardly out of them and also permit ready return of these cross bars. when the emptied receiver R is rep ac d.

From theforegoingit will'be seen that I have provided simple means for supporting a spent bobbin-receiver virrsuchmanner that it' can be readilyremoved and replaced merely by a sliding movement of thecrossbars .40 and 4| with respect to the guideways providedtherefor on both the preferred and modified forms of the supports. Itwillalso be seen that the spaced cross bars. 40,. and Al cooperate with. the guideways to prevent .vibration. movement of the. receiverR, and at the same time provide a convenient hand hold by which the receiver canbe. removed from its support.

.In.the. modified formofthe invention the suplatter relatively. to thepath traversed by the. de-

scending depleted bobbin, these adjustments be- .ingbothgangular and-longitudinal relatively to the supporting. stud. 5
